4 Claims.

ll/lyinvention relates to the distribution of fuel to the cylinders of an internal combustion engine.

The object of my invention is to properly pro-- 5 portion the fuel from the carburetor or the like to the various cylinders of an engine preferably of the V type.

Another object is to thoroughly gasify said fuel and thus create a proper mixture before l proportioning the same to said cylinders.

Another object is to provide a manifold that is simple, durable and of such construction that the same may readily be attached to the present type of engine.

l These and other objects are clearly shown in the specification and drawing of which Fig. l is a plan View of my manifold showing the intake port at the top and at the center thereof for connecting with the carburetor, outlet ports positioned approximately equi-distant to equal numbers of inlet ports of the cylinders, and passageways for directing said fuel to said inlet ports.

Fig. 2 is a longitudinal section taken on line 2-2 of Fig. 1 showing the fuel entering the intake port from the carburetor into a chamber in which said fuel is divided and mixed and then passed thru outlet ports at each end to the inlet ports of the cylinders, and also the means for 30 heati-ng said fuel chamber;

Fig. 3 is a bottom view showing the outlet ports at the bottom of my manifold which are positioned to register with the inlet ports of the engine;

35 Fig. 4 is a fragmentary plan View with parts in section on the line 4-4 of Fig. 2 to show the proportioning of the fuel at each end of the chamber to the inlet ports of the cylinders and also heating chamber and the inlet and outlet 40 ports therefor;

Fig. 5 is an end elevation taken on the line 5 5 of Fig. 7 showing my manifold as mounted on a, V type engine and the owing of the fuel from the compartment thru the passageways to 45 the inlet ports of the engine;

Fig. 6 is a section taken on line 6-6 of Fig. 4, more clearly showing the heating chamber and the inlet and outlet ports therefor;

My manifold as a consists of a single casting b 50 designed to be substituted for the manifold in present use on the Ford V-8 engine but embodying features that more efficiently condition the fuel and distributes the same equally to each of the cylinders.

55 A rectangular compartment c located at the (Cl. 12S-52) top of the casting b extends longitudinally thereof. The area of said compartment is determined to contain a suicient supply of fuel for all of the cylinders of the engine regardless of varying conditions such as slow or high speed of said en- 5 gine.

An inlet port d, centrally located at the top of the compartment c connects with a fuel feeding device such as a carburetor e. An outlet port f at one end of the compartment c is positioned equi-distant from the inlet ports o-f a determined number of cylinders and connects with a chamber y therebelow extending transverse of the casting. Said chamber is provided with outlet ports h iiush with the bottom of the casting and alin- 15 ing with the inlet ports z" of the engine i, see Fig. 5. Thus a sufficient supply of fuel in said chamber will be constantly at hand for equal distribution to the cylinders as required. A similar port f at the opposite end of the compartment c connects with the chamber y provided With outlet ports h alining with the inlet ports of the remainder of the cylinders.

The compartment c and the chambers y-g are so formed as to provide for a heating compartment j having an inlet port lc and an outlet port lc for the passage of a desired amount of exhaust gases by-passed from the regular exhaust manifold.

The properly proportioned air and fuel oil upon entering the compartment c strike the bottom c which, being heated, causes the globules of oil to vaporize and thus mix properly with the air which in turn is heated. The vacuum pull from each of the sets of cylinders being equal, the said fumes and air are divided and now in equal amounts to the chambers y-g, which are also heated to more thoroughly condition the fuel.

I claim:

l. A fuel conditioning and proportioning intake manifold for V-type motors, comprising a single unit casting, a compartment positioned longitudinal and central thereof and a fuel intake port therefor, a chamber of substantial varea positioned transverse of said casting and connecting with one end of said compartment, thereby forming a T having outlet ports at one side registering with inlet ports in one of the cylinder blocks and outlet ports at the opposite side for registering with inlet ports of the opposite cylinder block, and a similarly positioned cham.- ber .at the opposite end of the compartment having outlet ports' connecting with the remaining inlet ports of the cylinder blocks.

2. The combination described by claim 1 in- 55 10 ing, thereby forming Ts at each end of said compartment, ports in said chambers registering with inlet ports in each block in such a manner that .an abundant supply of fuel is available for each of the cylinders under varying conditions.

15 4. A fuel conditioning and proportoning intake manifold for a V-type engine, comprising a casting, means for securing the same to each of the cylinder blocks, a compartment longitudinal of said casting, an inlet port central at the top thereof, a chamber at each end of said compartment and approximately the Width of said casting, thereby forming Ts at each end of said compartment, ports in said chambers registering with inlet ports in each of the cylinder blocks in such a manner that an abundant supply of fuel is available for each of the cylinders, and a heating chamber under said compartment and between said chambers whereby the fuel is properly conditioned before being equally distributed to the cylinders.
